3.3. Promotion of Tube Wells

In the late 1970s or in the beginning of 1980s, the Bangladesh government supported by the United Nations Children's Fund, UNICEF initiated a mass project installing shallow tube wells (STWs) to provide safe drinking water to the rural population suffering from a number of waterborne diseases such as diarrhoea and cholera due to contamination of drinking surface water.

In the late 1970s and early 1980s, Bangladesh faced significant issues with waterborne diseases, largely because people were relying on surface water from ponds and rivers, which was often contaminated. To tackle this public health crisis, the government, supported by UNICEF, initiated a project to install shallow tube wells. These wells would allow access to groundwater, which was considered safer for drinking. The goal was to reduce the incidence of diseases like diarrhoea and cholera that resulted from drinking contaminated surface water.

Think of a community that relies on a muddy pond for drinking water, which often gets polluted. By setting up a series of clean, deep wells around the community, just like installing faucets in a kitchen, residents can get clean water directly without the risk of getting sick from what’s in the pond.

Now, more than 80% Bangladeshi population depends on tube wells for drinking water. The impact of this initiative was significant, as nearly 80% of the rural population started using tube wells for their drinking water needs.

The promotion of tube wells led to a dramatic shift in how people accessed drinking water in Bangladesh. As a result of the efforts to install these wells, over 80% of the rural population began using tube wells. This shift not only improved access to drinking water but also significantly reduced the rates of waterborne diseases in areas that had formerly depended on unsafe surface water.

Imagine a large town where the majority of people fill their bottles from a reliable water fountain instead of using dirty river water. Over time, as more people switch to using this clean water source, the overall health of the community improves significantly, with fewer people getting sick from water-related illnesses.

When 80% of people were using tube wells, scientists realized that they were now exposed to another disaster: arsenic contamination. If you drink arsenic-contaminated water, it will severely affect your health, making you vulnerable to cancer.

While the transition to tube wells initially solved water safety issues, it also introduced a new problem: arsenic contamination of groundwater. Research revealed that the water from many of these tube wells contained high levels of arsenic, a toxic substance that can lead to serious health issues, including cancer. This situation highlighted the unintended consequences of the tube well initiative that needed to be addressed.

Imagine that a community switches from drinking from a contaminated pond to filling their glasses from a filtered faucet. However, unbeknownst to them, the filter is defective, and the water contains harmful substances. Initially, they feel healthier because they are not drinking pond water. Over time, they start experiencing health issues because of the new contaminants in their supposedly 'clean' water.

Some people proposed community-level water supply ponds and filter systems to cope with water scarcity. The idea involved collecting pond water, filtering it through sand filters, and then distributing it as safe drinking water.

In response to the dual problems of arsenic contamination and water scarcity, some communities explored alternative solutions. One idea was to create community-level water ponds that could collect water and then use sand filters to purify it for drinking. However, these methods faced significant challenges regarding maintenance and effectiveness, leading to questions about their overall success and implementation in rural areas.

Consider a town that decides to build a large community pool for everyone to share. They plan to clean the pool with a filtration system. Initially, people are excited to use this shared resource, but when the filtration system needs repairs and becomes neglected, the water quality diminishes, and people begin to hesitate to use the pool for bathing, let alone for drinking.

People are not very encouraged to adopt alternative drinking water solutions due to a variety of factors, including habit, lack of awareness, and existing poverty.

Despite the availability of alternative water solutions, many individuals in affected communities are hesitant to adopt them. This reluctance can stem from deeply ingrained habits, a lack of awareness about health risks, and the challenges of poverty that take priority over water quality concerns. As a result, people continue using contaminated water sources because they are accustomed to them or lack the resources or knowledge to switch to safer alternatives.

Think about someone who has always used a particular route to get to work. Even when a new, safer road opens up, they may hesitate to switch paths because they are comfortable and familiar with the old route. Similarly, if communities have historically used certain water sources without apparent problems, they may resist change despite new evidence suggesting that these sources are unsafe.
